FireCore announced today that it successfully jailbroke the Apple TV 2 (not the new Apple TV 1080P that released earlier this month). The jailbreak is tethered, which requires the Apple TV to be connected to a Mac/PC when first powering it on (only once). You also have to pay fireCore $30, but it has been plenty good about updating.

What’s new in the 5.0 AppleTV software? Should I update?
